  • Title: Reticulocyte protein synthesis: response of ribosome fractions to polyuridylic acid.
    Author: WEINSTEIN IB, SCHECHTER AN, BURKA ER, MARKS PA.
    Journal: Science; 1963 Apr 19; 140(3564):314-6. PubMed ID: 13999647.
    Abstract:
    Reticulocyte ribosomes with sedimentation coefficients greater than 100S ("heavy" ribosomes) appear to be considerably more active in hemoglobin synthesis than are 78S ribosomes. When assayed for the ability to synthesize polyphenylalanine in the presence of polyuridylic acid, the 78S ribosomes and "heavy" ribosomes have similar activities. Polyuridylic acid inhibits incorporation by "heavy" ribosomes of amino acids other than phenylalanine.
